1) DISCONNECT POWER and remove the pads as shown on page 28.
2) Motor is located in center of unit. Switch box is located in upper left.
(Figure 1) Locate motor harness wire secured to fan bracket assembly
using plastic ties. Cut and remove plastic wire ties. DO NOT CUT
ELECTRICAL HARNESS WIRES.
3) Remove switch box cover. (Figure 2) Unplug motor wire harness
connector. Push rubber grommet on motor wire harness through switch
box opening and remove motor harness from switch box.
4) Loosen four (4) bolts that secure the motor mounting plate. This will
allow the motor plate to move up or down. Loosen and remove the
belt from the motor pulley. (Figure 3)
5) On front of motor mount, remove belt pulley by loosening setscrew.
Remove four (4) lock nuts securing motor to mount. Remove motor by
sliding straight back out of mounting holes.
6) Install new motor by reversing steps above. (A.) Install new motor into
motor mount and install four (4) lock nuts to secure motor to mount,
but do not tighten. (B) Install motor pulley on motor shaft and align with
fan blade hub pulley. Install fan belt on fan blade pulley by sliding motor
plate away from the fan hub. Visually align the motor pulley and fan
pulley by using the belt as a reference. (C) Adjust the motor pulley in or
out to align. Tighten the motor pulley setscrew. (D) Apply pressure
on the motor to further tighten the belt being careful not to over tighten.
(About 15 pounds of pressure is sufficient). Complete tightening of the
four (4) motor plate bolts. (E) Thread terminal end of motor wire through
switch box opening and plug connector into switch connector.
PROPERLY RESEAT RUBBER GROMMET SEAL ON HARNESS AT OPENING
IN SWITCH BOX TO KEEP WATER OUT OF CONTROL BOX. FAILURE TO
DO SO COULD CAUSE ELECTRICAL SHOCK. (E) Replace switch box
cover. (F) Secure motor wire harness to fan bracket assembly using new
wire ties. (G) Replace pads by installing from outside in toward center
replacing center pad first.
7) Reconnect the unit power and test motor.

1) DISCONNECT POWER and remove pads as shown on page 28.
2) Motor is located in center of unit. Switch box is located in upper left. Locate motor harness wire
(Figure 1) secured to fan bracket assembly using five plastic wire ties. Cut and remove plastic wire ties.
DO NOT CUT ELECTRICAL WIRES.
3) Remove switch box cover. Unplug motor harness wire connector. Push rubber grommet on motor wire
harness through switch box opening and remove motor harness wire from switch box. Disconnect motor
harness at the quick release connector. (Figure 2 NEXT PAGE)
4) Remove the screen from the front of the unit to access the fan side of the unit.
5) Loosen the nut from the threaded motor shaft and take the fan blade off.
(Figure 3 NEXT PAGE)
6) Locate the 8 bolts (2 on each arm) holding the motor in place. (NOTE: the
position of the motor on the mounting arms. Make sure to mount it in the
correct railings of the motor housing and at the correct distance from
front or back on all four arms to ensure stability and alignment)

FAN SYSTEM
This section is divided into the two categories of fans used on all PORT-A-COOL® models: Direct Drive and
Belt Drive. Both have some symptoms in common, and both have problems that are particular to each.
